Big breakthroughs in the evolution of the brain and its connection to the stomach

The human brain is the most complex object in the known universe, but key parts of its evolutionary history, from the earliest brains and nervous systems on the planet to more recent changes in our lineage, remain shrouded in mystery.  New studies shed light on both ends of the spectrum, answering an over one hundred… Continue reading Big breakthroughs in the evolution of the brain and its connection to the stomach

Key moments in humanity’s early and more recent history remain written in our DNA

Two new studies illuminate long standing mysteries in our evolutionary and cultural history.  Why were early humans smarter and more adaptable than our Neanderthal cousins even though their brains were about the same size?  When and where did the earliest Indo-European languages emerge leading to what about half the world speaks today?  DNA is a… Continue reading Key moments in humanity’s early and more recent history remain written in our DNA

You have the eye of a fish and the DNA of a Neanderthal, but what are you doing with that big brain?

It’s been a huge couple of weeks in evolutionary biology:  Three teams of scientists, studying three separate periods spanning 450 million years make surprising discoveries about our bodies, our culture, and our ancestors. The human eye is an amazing organ, the origins of which are ancient and shrouded in mystery.  Complex eyes, from people to… Continue reading You have the eye of a fish and the DNA of a Neanderthal, but what are you doing with that big brain?
